sears craftsman door opening problem
I have a sears craftsman model 139.53628srt. Door was working fine, came home and all of a sudden door will not go down when hitting the one button on the wall. door budges and then returns. I get the blinking bulb. Tried adjusting the eyes no results. both car remotes get nothing from when pressing. When I hold the one button on the wall the door goes all the way down. If I let go before it gets to bottom it comes back up. I noticed only one of the eyes have a green light on. HELP!
